The brachial plexus palsy is a rare complication of a clavicle fracture, occurring in 0.5% to 9.0% of cases. This condition is caused by excessive callus formation, which can be recovered by a spur resection and surgical fixation. In contrast, only seven cases have been reported after surgical reduction and fixation. A case of progressive brachial plexus palsy was observed after fixation of the displaced nonunion of a clavicle fracture. The symptom were improved after removing the implant.

Distance from the 1st rib to the clavicle of the non-union side changed from 41.2 mm (A, preoperative) to 28.5 mm (B, postoperative). After implant removal (C) displacement recurred and the distance increased to 42.1 mm. Three-dimensional computed tomography shows that bony spur alone coraco-clavicular ligament (A) was completely removed (B, C). The level of the scapular spine migrated 24.6 mm upward after fixation (B) and returned to the preoperative state after implant removal (C).
